7 Specification of Letters Patent. Application alee September 5, 1912. Serial No.7-18,662.

Patented Nov. 4, 19153.

To all 1v710m1't may concern: Be it known that -I, J ACOB ATLAS, a citizen of the United Statesfresiding at Vista Grande, in thecounty of San Mateo and State of California, have invented a new'and useful Interchangeable Window-\Veight, of

Y which the following is a specification in such .full and clear terms as will enable those skilledin the art to construct and, use the same.

This invention. relates to an interchangeable window weight audits object. is to provide means whereby the expense of makmg such weights may be greatly reduced as well as to provide means whereby .a better weight may be produced. It will be understood by those skilled in the art that the ordinary cast iron window weights are very brittle and that the cast iron is so shaped that there must be a conof different sizes of weights to accommodate them to all sizes of windows. Moreover, whenever a weight is broken it is of no value since it seldom is then of the proper weight to be used to bal- 'a'nce the window.

With the present invention it is contemplated that but a limited number of difi'erent sizes of weights shall be made, smaller weights being made by omitting some and larger wei hts being made by adding such a number 0 smaller pieces as may be demanded to make up a weight to balance a given sash.

, In the drawings in which the same numeral of reference is applied to the same portion throughout the several views, Figure 1 is a side elevation of a completed weight having four sections, Fig. 2 is a vertical sectional view of the weight illustrated in Fig. 1, Fig. 3 is a side elevation of the top casting, Fig. 4 is. a side elevation of the bot- 'tom casting used, Fig. 5 is a side elevation one of the intermediate weight portions, lhg. 6 1s a plan view of the weight shown in Fig. 1, and Fig. 7 is a horizontal sectional ,view'of the weightillustrated in Fig. 1.

It is contemplated that theweight shall have a bottom piece 1 which is threaded as ai i to fit into the grooves 3 at the edges of the bottom piece 1. This bottom priece W111 be dropped into the receptacle 4 0m the top and thereafter a tube 5 is placed against the bottom piece 1 and the receptacle 1 is then filled with a suitable plastic material as cement and sand, which plastic materialis then allowed to harden.

Atthe upper end the receptacle a receptacle 6 which receptacle has a fiat bottom 7 and depending flanges 8 "with an overhanging shoulder 9 to prevent the passing weights from tearing out the edges of the receptacle 4. The receptacle this of a different length from the receptacle 4, but it.

is likewise filled with a cementitious material 10 and it'hasa tube 11 extending therethrough.

Above the receptacle 6 there is a receptacle 12 in every respect the same as the re-.

ceptacle 6, save that it is of a diflferent length from the receptacles 4 and 6. Above the receptacle 12 there is a rece tacle 13 which has a flat bottom 14: and anges 15 and which fit the top of the receptacle 12. This receptacle 13 has a pyramidal top 16 which fits into the top of the receptacle 13, while at the same time it is smooth atthe edges to prevent it from interfering with other weights against which itfmay swing.

The receptacle 13 has a tube 17 extending.

from the bottom 14: into the tube 16, said tube being held in place by means of a body of plastic material 18 which fills the lower portion of said receptacle. The object of leaving the receptacle. 13 partly empty is to provide means whereby the weights may be increased to exactl balance a given sash, that is, a number 0 pieces as for example 4, 6, l2 and 13 may all be assembled together by means of the eye-bolt 19 which passes through the several tubes in each section,

but it may befound that such a weight does not quite balance the sash, in which event the receptacle may be filled with sand or any suitable material until the weights used exactly balance the given sash.

The exterior of the several weight members may be made of any suitable sheet metal or other sheet material suitably seamed over as illustrated at 20 and the cross section may be either a rectangle, or a circle or any other form.

Having thus described my invention what eral receptacles and secured in the bottom 10' I claim as new and desire to secure by Letreceptacle, substantially as described. ters Patent of the United States, is as fol- In testimony whereof I have hereunto set lows: my hand this 26" day of August Al i-1912, 5 An interchangeable Window weight 'comin thepresence of two SllbSCIibBfifWlt-HGSSGS. prising a plurality of weighted receptacles, JACOB ATLAS.
